Littelfuse P0640SCLRP, Thyristor, 500A 2.2mA

Littelfuse DO-214AA SIDACtor solid state protection devices protect telecommunications equipment such as modems, line cards, fax machines, and other CPE.SIDACtor devices are used to enable equipment to meet various regulatory requirements including GR 1089, ITU K.20, K.21 and K.45, IEC 60950, UL 60950, and TIA/EIA-IS-968 (formerly known as FCC Part 68).

All measurements are made at an ambient temperature of 25°C. Ipp applies to -40°C through +85°C temperature range.
Ipp is a repetitive surge rating and is guaranteed for the life of the product.
Listed SIDACtor® devices are bi-directional. All electrical parameters and surge ratings apply to forward and reverse polarities.
Vdrm is measured at Idrm.
Vs is measured at 100 V/μs.
Special voltage (Vs & Vdrm) and holding current (Ih) requirements are available upon request.
Off-state capacitance is measured at 1 MHz with a 2 V bias and is a typical value.
